I wanna know if there is a formula/algorithm to get the first common number from multiple sequences. For example:
S1 = 2, 4, 6, 8, 10, 12, ...
S2 = 3, 6, 9, 12, 15, ...
S3 = 4, 8, 12, 16, ...
First common number is 12
If there is a way please let me know, because I've been looking for hours and can't find anything to solve this.
